Particlesy

Witam!

Mam taki oto skrypt i gdy zmieniłem wersję z 1.7 na 1.8 to przestał on działać (uproszczona wersja):

command /a:
	trigger:
		spawn 100 of particle heart:2 offset by 0, 0.5, 0 at player

Błędów nie ma lecz wywala błędy w konsoli:

Mógłby ktoś pomóc? Nie wiem na czym polega problem gdyż skquery działa (gui działa normalnie)

Z góry dziękuję
